Magnetmotor from Perendev modified by Calloway

Magnetmotor consists only out of 25x25x25 N52 Magnets and 0.25mm thick Mu metal shielding foils on the outside of the rotor to overcome the sticky point. It is important not to extremely bend the mu metal since it will loose its high permeability due to locally destruction of the atomic lattice. Also be aware not to get magnetically saturized foil. So do not stick the foil too close towards the N52 magnets. The foil should be placed between the gaps of neighbouring rotor magnets on the outside wheel diameter in order to redirect the rotor magnetic field and to avoid counter force of the rotor. Without the shielding the rotors will stop moving and you can observe that there is no fixed direction of rotation.Before stop the rotors move slightly to the left and back to the right. You will need to start the magnetmotor with minimum 2000 rpm. One can plug a drilling machine to the axis with an adapter. Be aware not to run it in idle state. You can put an aluminum stripe around the rotor which functions as eddy current brake. As next step you can put coils around the rotor for gaining the induced voltage due to the alternating magnetic flux. In the moment I try to increase the torque by adding magnetic shielding around the stator magnets. I will try it with a mixture of bismut and graphite powder being poured into a silicon caoutchouc form at a temperature of 280°C. The shielding is only removed at north or south pole and 10 mm thick. I try to find out how weak a magnet should become so that a bismuth layer of 10 mm thickness is able to suppress the entire magnetic field. Or other way around how thick has a bismuth layer to be for completely shielding a N52 Magnet.
